Application filed September 29, 1920. Serial No. &13,593.

To all whom 'it may conccm; p Be it known that I HENRY M. MINNIs, acitizen of the United States, residing at Wylie, in the county of Collinand State of Texas, have invented certain new and use- -ful Improvementsin Cistern Outlets, of which the following isa speeification.

This invention relates to new and useful improvements in cisternoutlets. It is eustomary in certain localities to cel lect rainwater inan outside cistern supported above the ground. These cisterns areusually made of thin sheet metal and conse-` quently in cold weatherthewater treezes inwardly 'rom the wall of the cistern and in the summertime the water nearest the wall has a higher temperature, especiallywhere the cistern is exposed to the rays of the sun. These eisterns areused 'in loealities where the temperature seldom goes below the zeropoint, but often treezing weather is experienced. Under such conditionsthe water in the cistern will not be frozen at the center, but will befrozen next to the wall.

The purpose of my invention is to provide an outlet which will receiveits supply of water at the center of the cistern thus making it possibleto draw water in freezing weather and get cooler water in warm weather.These cisterns are generally provided with a faucet inserted in thewallof the cistern and consequently when the water is frozen, no water canbe drawn oli' and the hottest water is discharged in warm weather.

It is also thepurpose of my invention to arrange the outlet in suchmanner that the connections will drain when theoutlet is closed.

In carrying out the invention I arrange a valve at the center of thecistern and eXtend a pipe radially from the same through the wall of thecistern. The valve is suitably supported above the bottom of the cisternand a water tight connection is made at the point where the pipe passesthrough the wall of the cistern. A faucet is mounted on the end of pipeoutside of the cistern. The valve stern extends through the pipe and thefaucet and has an Operating element on its outer end; Bythis arrangementthe Valve at the center of the cistern may-be opened and closed. Whenthe valve is closed no water can enter the pipe and the faucet, andtherefore the same will drain.

The invention will be more readily understood from a reading of thefollowing specification and by reference to the accompanying drawings,inwhich an example of the invention is shown, and wherein Fig. 1 is asectional View showing a portion off a cistern and an outlet constructedin' end. The casing has a screw threaded boss 12 dependingefrom itsnnderside receiving the upper screw threaded end of a pedestal 13 havinga base fiange l iwhich is mounted on the bottom 15 of the cistern. Thepedes- .tal is arranged so that the face or seat `ll will be at thecenter ot the cistern. The outer end. of the casing 10 is connected witha radially extending pipe 16 by a union 17. The pipe extends through theside wall lS of the cistern and is scr'ew threaded so as to receive abushing 19 which fits snugly in an aperture 20 in the wall 18. Thebushing is reduced where it passes through the wall 18 and is screwthreaded to receive a packing nut 21. A paeking .washer 22 fits over thereduced end ot the bushing and is forced against the inner side of thewall 18 by the nut 21. By this arrangement a water tight joint is had.

A wing valve 23 has a sliding fit in the casing 10, and is providedwithan enlarged head l having a fiat underside receiving a gusket 25 adaptedto close against the face ll. When the valve is displaeed inwardly a wayfroni the face ll, the water from the eistern will pass into the iasingand between the wings of the valve and then into the pipe 16. Avalvestem 26 extends from the valve a through the pipe as is shown in Fig. 1.On the outer end et the pipe a T-shaped faucet 27 is threaded. A plugQSis screwed into the outer end oi" the 'aucet and this plug is internallyscrew threaded to receive the screw threaded portion 29 of the valvestem. A packing glandnut 30 is serewed onto the plug and receives apacking 31 through which the stem 26 extends. A hand wheel or otherOperating` element 32 is fastened on the outer end of the valve stem.

It will be seen that by turning the hand wheel 32 the valve stern 26will undergo a longitudinal movement owing to the engagement of itsscrew threads 29 in the plug 28.

By this operation the gasket will either he brought into engagement withthe i ace ll' to close the valve, or will he displaced from said face toopen the ValVe. When the ValVe is opened the water from the center ofthe cistern will pass into the casing 10 and through the pipe 16, to thefeucet 27 from which it will be discharged as is evident. It will beseen that when thevalve 23 is closed any water in tle pipe 16 and taucet27 will dinin out. If desired the pipe 16 may he given a siight inclineoutwardly so as to be sure and drein all of the water in the parts 10,lG and 27, however, this is not essential. The valve is supported abovethe bottom of the cistern so as not to become filled with sediment. ltis quite obvious that with e cietern 8 feet in diameter extremely coldweather would be necessary to freeze the water :tt the center, and thuswith this outlet in the cistern a supply of water in Very cold weathercould he had. It is also obvious that the water would be of a lowertemperature at the center ot' the cistern in warm weather, therefore,coole` water may he had under these conditions. By removing the plug 28the casing, pipe and taucet may be fiushed out when desred.

tenk and projeeting through the side thereof to the exterior of theseine, a coupling for detachahly connectng the end of the ppe und theend of the valve casing, means for ettecting a water tight oint betweenthe pipo and the wall of the tenk, a T coupling mounted upon the outerend o said pipe exteriorly of the tenk, a`valve body slidably mountedwithin the valve easing and having an enlarged head at one end thereofto engage the end of the Valve casing, said valve body hm'- ing`longitudinal grooyes, a stem connected with the inner end of the VuiVeand extending through the pipe and l'aving screw threaded engagementwith u portion of the T-coupling, and means to turn the stem.

In testimony wherect I my signature.
